Long Distance Flyers! 

These 3 species were all found within a 5 day period!

The Wandering Glider is considered to be the most widespread dragonfly on the planet with good populations on every continent except Antarctica. I found my first one along the edge of Canatara Beach today. They make an annual multigenerational journey of 18,000 kilometres and are believed to be the world's "longest known distance insect traveler". Due to its worldwide distribution, this species has occurred on many stamps!

I often struggle to identify Sulphur Butterflies. This one seemed a little different so I snapped several photos. Upon checking the identification guide, I learned that the Little Yellow is a mainly tropical and subtropical species that can migrate northward! Sometimes several individuals arrive in Ontario and can occasionally breed but it does not overwinter in our province.

Thanks to our friend Dale, we were able to see a pair of Marine Blue butterflies in south Lambton last weekend! They are only 25mm in width. It is a very rare migrant to Ontario and the last time this species was recorded in Ontario was in 2008. It's permanent range extends from Guatemala to the southern U.S. 

Both of these photos are of the same individual but I understand that we found a male and a female Marine Blue! This species has twice established temporary breeding colonies in Ontario: Point Pelee in 1993 and Toronto in 2008. The ROM Field Guide to Butterflies of Ontario, Peter W. Hall et al.
